\abstract{
Public health documents contain a rich set of topics and keywords that cover various aspects of a nation's health system. Each topic is characterized as a distribution over vocabulary from which we extract the keywords. Visualizing this topic structure allows the reader to have an intuitive and convenient overview of a usually lengthy report. In this paper, we describe \emph{ReportVis}, an interactive utility that uses nested bubbles to represent topics, key words and their weights. We use a collection of US Health Reports issued by CDC from 2009 to 2012 as our exemplar corpus to demonstrate a interactive exploration of topics and their keywords in public health. We further introduce an animation mode to allow a dynamic view of topic evolution.
